Specification qf Letters Patent. Patented Feb, 24, 1920.

Application filed April 1r, 1919; .SerialNo. 289,235.

Be it known that I, FREDERICK MYExs, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Record-Needle Repointers, of' which the following is a specification.

This invention relates to improvements in devices for producing a smoothly finished conical point upon needles such as are used in "connection with sound reproducing machines; 4

The principal-object of the invention is to provide a neat, small and compact apparatus adapted for manual operation, in

which a needle may berepointed ina rapid and easy manner, the; device bein a desire able adjunct to a talking machine using disk records.

A further object is to provide a mechanism which will repoint a needle central with its axis, irrespective of its length-or condition, so that the same may be'used without scratching or damaging the record,

. and which will produce a point adapted for reproducing sound from records'in' a su- POI'IOI' 11131111812.

, These and other like objects are attained by the novel "construction and combination Figure 1 is a side elevational view show ing a needle repointing mechanism made in accordance with the invention. I r

Fig; 2 is a-front elevational view thereof,

and

Fig. 3 is an enlarged fragmentary sec tionalview takenthrough the needle hold- 1 ing device.

Referring to the drawings, the numeral 10 designates the base of the mechanism, the same being preferably provided with. a cushion-like felt pad llupon its'lower side so as to avoid scratching or defacing the surface upon which the machine is placed.

Fixedly engaged upon the upper surface of the base 10 is a metal stripl2, havinga vertical standard 14, bent outward at its upper end and formed so as to provide apair of forks 15, in which, pivoted upon the pin 16, is alever 17, having a front extending portion 18 terminating in an upturned finger catch 19.

Engaged with the opposite end 20. of the lever 17 is a coiled tensional spring 21, secured at its lower end to apin 22, extendin rearwardly. from the standard 14.

- he opposite end of the strip 12 is also turned vertically upward forming a front standard 24 and journaled in the standard of an abrading wheel 32, having a conical face for. purposes which will be hereafter described. Upon theopposite end .of the spindle 25, is fixed the hub 34, of a spur gear 35, .the gear meshing with a spur pinion 36, mounted on a spindle 37 rigidly secured in the lever'17, and extending toward the front of the machine.

The pinion 36 isformed witha sleeve 38,

, 14 and 24 is aspindle 25, held in position by having an annular enlargement 39,.termi .nating in a reduced head 40, bored axially to receive a needle 52, the head containing a conical recess 43, so that the straight portionof a needle may be readily entered and clamped therein by the thumb screw 44, the same having an enlarged knurled head which may be operated by the thumb and fingers. At the inner end of the cylindrical recess 45, formed in the sleeve 38 to receive the spindle '37, is also contained, acoiled compression spring 46, pressing outwardly a small lunger 47, against which the straight end 0 the needle'42 abuts.

Aspring arm548 is secured to the base by the clampscrew 49,the-sa me being curved and provided with an elongated opening 50 adapted to surround the head 48, and press against the annular enlargement 49, holding the sleeve, together with the gear,

' upon the spindle 37 on which it rotates.

h1g5? is secured upon the base uponwhich the thumb of the operators hand maybe placed, while the otherhand actuates the extending knob 30, communicating motion to the spindle 25,1otating the abrading wheel 32, and if the. lever 18" be depressed, by action of the fingers-the pinion 36 will engage with the teeth of the gear 35, thereby communicating rotary motion to the sleeve 38, which is held rearwardly by the action of the spring arm 48. The pivoted-gage arm 52 being pushed'to I one side, as indicated best in Fig. 2, a needle may be readily inserted in the conical entrance 33, whereupon the arm 52 is raised to a vertical position acting as a limit or gage for the point of the needle, which is pressed forward, due to the action of thespring 46, and then clamped by manipulating the p The lever 52 is thenmoved again to the side, the finger pressed thumb I screw 44.

upon the lever 18, guided by the projection 19, so as to bring the gearsinto engagement band cause'the conical end of the needle to combination with a base, apair of standards make contact with the revolving beveled surface of the abrading wheel .32, thereby repointing the needle in an obviousmanner.

Immediately upon releasing the lever 18 it is raised 'bv the pull of the spring 21, the screw 4 L relaxed and the needle removed, the operative position of'the sleeve being indicated by the broken lines in Fig. 1.

rrom the foregoing it Will be seen that a ing from the general spirit of the invention herein recited.

Having thus described my invention what I claim as new, and desire to secure by Letters'Patent, is

1. In a device ofthe class described, the

thereon, and a spindleijournaledin said standards, of an abradmg wheel secured upon said spindle, means for manually rotating said spindle, a lever journaled in one of said standards, a spmdleextendlng from said lever, a sleeve rotatable on said second spindle, driving connections between said sleeve and the first named spindle, means for normally raisin said second spindle, a head formed with said sleeve having a conically mouthed opening, means for clamping a needle therein and a swinging stop for locating the point of the needle. 7 Y

2; In a device ofthe class described the combination with a base, a pair of stamlards secured thereto, L a spindle "journaled'in said standards, means communicat ng rotary motion to said spindle, an abrading wheel se-v gearsecured upon said spindle at its opposite end, of a lever pivoted in oneof said standards .tOfIIlOVG, in a vertical plane, a spring. attached to said leverwhereby it is normally helu ,infa raisediposition, means forfdepressing said lever, a spindle rlgldly secured 1n said lever,'a sleeve rotatable on said second spindle, geared connections between said sleeve and the first named spindle,

resilient means for holding said sleeve onsaid second spindle, a head formed with'said sleeve adapted to receive aneedle,means for,
